Web12 sep. 2024 · Energy from a nuclear fission reaction produces hot, high-pressure steam that turns a turbine. As the turbine turns, electricity is produced. The major drawback to a fission reactor is nuclear waste. U-235 fission produces nuclei with long half-lives such as 238U that must be stored. WebThe first nuclear fission process discovered was fission induced by neutrons. Because cosmic rays produce some neutrons, it was difficult to distinguish between induced and spontaneous events. Cosmic rays can be reliably shielded by a thick layer of rock or water.
